Inventor: NEALE LEONARD
IPC: D02G1/16
Filed: 1959-02-09
Abstract: 883,304. Spinning and finishing yarns. COURTAULDS Ltd. Feb. 8, 1960 [Feb. 9, 1959], No. 4399/59. Class 120(3) Fancy yarn is produced by intermittently abrading a bundle of continuous filaments during its passage to a bulking, turbulent, fluid zone so that those filaments which have been cut by contact with the abrading mechanism are formed within the zone into neps or short slubs. In one process, a bondle of untwisted filaments of varying denier is withdrawn as a balloon from a rotating package and the filaments twisted thereby pass through nip rollers thence to a take-up package: a traverse mechanism moves an abrasive rod, e.g. of carborundum, into intermittent contact with a secondary balloon formed between two guide eyes above the main balloon. In other processes, a guide ring is provided in part with an abrasive surface or an abrasively surfaced guide is moved into and out of contact with the filaments. Specification 732,929 is referred to.

Title: Improvements in electric switches
IPC: H01H13/68
Filed: 1922-02-15
Abstract: 175,972. Hart Manufacturing Co., (Assignees of Hart, G. H.). Feb. 24, 1921, [Convention date]. Snap-action switches.-Relates to switches of the push-button or tumbler type in which the actuating member 7, Fig. 11, the support, Fig. 5, and the member 4, Fig. 6, to which the contact arms 19 are attached are all of U-shape, the detent 12 is cylindrical and the spring 16 is coiled round the pivot 11 of the actuator and of the switch arm carrier and embraces with its outer ends 17, 18 the cross members of these two parts. If the switch is of the double push-button type, Fig. 1, depending parts from the buttons are snapped into holes 24 in the actuator, Fig. 11; while in the case of a tumbler switch, a link 29 is snapped into a hole 31 in the actuator. In one position of rest, the detent 12 is held at one end and, at the other, passes first through a slot in the actuator, Fig. 7, then through a slot 14 in the support, Fig. 5, and lastly into a recess 6 in a slot in the carrier member 4, Fig. 1. Depression of the left-hand button 21, Fig. 1, turns the actuator counter-clockwise and tensions the spring 16, but the member 4 is, at first, unable to move, as the bottom of the wall 5 of the recess engages the detent below its centre. Near the end of the travel of the actuator, the curved portion 9<1> of the slot in it engages the detent to move it downwards sufficiently to cause the wall 5 to press on it above its line of centre, when this pressure forces it lower still and finally brings it collinear with the concentric slot in the member 4, which member is then flung over bv the tensioned spring till stopped by a shoulder 3 on the support 2. Removal of the finger from the button allows the actuator to set back slightly, when the lower wall 9 of the slot in it pushes the detent into the recess 6 at the other end of the slot in the carrier 4. In the case of the tumbler switch, Fig. 7, a housing 34 projects up from the supporting plate 33 through the cover, and the arm 28 pivots round a projection on the plate 33.

Title: Control apparatus for a broadcast stereophonic signal receiver system
IPC: H04B1/16
Filed: 1963-02-05
Abstract: 992,684. Stereophonic radio receiving systems. HAZELTINE CORPORATION. Feb. 5, 1963 [Feb. 26, 1962], No. 4682/63. Heading H4L. A radio receiver for stereophonic or monophonic signals is provided with means for deriving an indication of the presence or absence of stereophonic signals in the received signal whereby the stereophonic circuits are disabled in the absence of a received stereophonic signal. As shown in Fig. 1, in a system in which the L + R signal frequency modulates a main carrier and the L-R signal amplitude modulates a 38 kc/s. subcarrier which is suppressed, a 19 kc/s. pilot signal being transmitted, the output of the frequency discriminator. 13 is supplied to a known type of stereophonic adapter 14 comprising a local oscillator and phase-splitter 18 synchronized by the 19 kc/s. pilot signal to provide a 38 kc/s. switching signal for demodulating and separating the L and R signals at 21. The composite stereophonic signal is supplied via a filter 19 blocking the pilot signal and a filter 20 blocking an additional (storecast) signal, to the demodulator 21, the L and R signals being supplied via a deemphasis network 22 to the respective output circuits. The output from 13 is also supplied via an amplifier 31 having an output circuit 36 tuned to select the 19 kc/s. pilot signal which is supplied to a detector 37 providing one of two voltage levels depending on the presence or absence of the pilot signal. The output of the detector 37 is supplied to a D.C. amplifier 40 which is arranged to be biased negatively when the pilot signal is present so that its rise of anode potential causes a neon indicator 52 to strike. This bias is removed for monophonic signals so that the anode potential of valve 40 is decreased and the neon lamp 52 is extinguished, a potentiometer 50 being adjusted so that the voltage at the movable tap is higher than the anode voltage of the valve 40 but lower than the maintaining voltage of tube 52. Thus diodes 47, 48 will conduct and the tank circuit of oscillator 18 will be heavily loaded by capacitors 51, 45, 46 so that the oscillator will be inoperative. When the stereophonic signal is present, diodes 47, 48 will be reverse-biased due to the increase in anode voltage of the valve 40, thereby removing the loading from the tank circuit of the oscillator 18. Any variation of the reverse bias which could cause a phase shift in the oscillator 18, is prevented by the tube 52 acting as a voltage regulator. In a further modification, Fig. 3 (not shown), in which the stereophonic adapter is of the type comprising a frequencydoubler providing a subcarrier signal for combination with the L-R sidebands, the recombined L-R signal is supplied to a double diode demodulator and matrix circuit together with the L + R signal, the connection between the recombined L-R signal and the demodulator being controlled via a diode switch in a similar manner to that shown in Fig. 1.

[Class 106 (ii)] Cans are tested for leakage when the ends are fitted to the bodies and before being finished by soldering. The cans 23 to be tested are supplied to a runway 33 and fed by a screw conveyer 34 to pockets 22 in the periphery of a turret disc 21 keyed to a sleeve 9 in. one with the hub of a disc 10 which rotates on a fixed shaft 2. Keyed to the sleeve 9 is also a toothed wheel 8 driven by a pinion 7 on a shaft 3 which may be clutched to a driving pulley 4. The wheel 10 has radial ports 17 adapted to communicate with radial ports in a coned boss 15 and the shaft 2 and thence with a longitudinal port 12 to which suction may be applied. After the can is fed to the turret its open end is pressed against a pad 18<a> on the disc 10 by a spring-pressed plunger 24 advanced by engagement of its end 28 with a fixed cam. A lateral port from the port 17 passes through the pad, and immediately afterwards the ports 17, 15 register and the interior of the can is exhausted. If leaky, the can drops to a shoot beneath the wheel when the plunger 24 returns under the influence of its spring on leaving the cam. The sound cans are carried around and as soon as they begin to rise the port 16 in the hub registers with the port 17 and the can is again submitted to a vacuum. It is then carried to a deflector 30 which deflects the can on to a discharge runway 31. A bore 39 may relieve the vacuum, the can being held by a plate 38 concentric with the turret. The deflector may be given a reciprocating movement so that the cans are pushed from the pads. When the cans are not being taken away fast enough by the discharge runway a bar is displaced by the weight of the cans packing up and a clutch released in the drive of the screw 34. The cans are tested after the ends have been pushed on in a " header " machine and before they are bonded by soldering.
